In 1979, a 16-year-old girl named Pem Michelle Yates-Briggs left her home in Oregon City, Oregon. She was born on March 31, 1963. Pem, a white female with blonde hair and brown eyes, stood between 5'3" and 5'6" and weighed between 110 and 125 pounds. She had a distinctive cleft chin and a crooked front tooth. Pem embarked on a journey to California with the intention of finding her father. The last known communication from anyone regarding her whereabouts came on June 1, 1979, when a police department in California contacted her mother. The police inquired whether Pem had permission to be in California, to which her mother affirmed she did. This was the final indication of Pem's location. For reasons that remain unclear, Pem Michelle Yates-Briggs was not officially reported as a missing person until March of 2024, a staggering 45 years after she was last heard from. The circumstances surrounding this significant delay in reporting are not publicly detailed. The lack of an immediate investigation has undoubtedly complicated the efforts to piece together the timeline of her disappearance and uncover what happened to her after that final phone call. The case is being handled by the Clackamas County Sheriff's Office in Oregon. The passage of over four decades has left a cold trail, with many questions and few answers. The specific police department in California that contacted her mother remains unknown, which is a critical piece of information that could have provided a more precise last known location. It is also not publicly known how she was traveling. The case of Pem Michelle Yates-Briggs is a deeply troubling one, highlighting the vulnerability of a young person and the painful uncertainty that can linger for a family for decades. The investigation, now active after a long period of dormancy, faces the immense challenge of solving a mystery that is nearly half a century old.
